Hi,
I am designing a Power supply having following parameters:
Input Voltage: 85VAC - 265VAC
Input Frequency…
Part Number: UCC2894 Can UCC2894 use on "external sink circuit" to VREF input?
I worry about possibility to increase VREF voltage by external sink.
Is there no problem to VREF connect from external sink circuit?
Best regards,
Satoshi
Part Number: UCC2894 One customer is planning to addition the external circuit for sink current flow to VREF pin.
Please let me know about two points below,
①Is there spec for VREF maximum sink current?
②Is UCC2894 specification(Vout accuracy, ripple…
Part Number: UCC2897A Other Parts Discussed in Thread: UCC2894 Hello,
I designed an 'Active clamp forward converter' by using the UCC2897A Advanced Current-Mode Active-Clamp PWM Controller. I want to start at 212Vdc input, when I was giving the…
Part Number: UCC2894 Overcurrent or short circuit occurs in the UCC2894 output stage, causing the MOSFET driver and MOSFET to burn out. How to use CS pin to improve detection sensitivity and achieve protection.
Part Number: UCC2894 I would like to konw about UCC2984.
Is there any failure about foward DC/DC convertor using UCC2984 without Preload rsistor at output stage, when no load?
Is there any recommended value of Preload resistor for UCC2984?
Part Number: LM5026 Other Parts Discussed in Thread: UCC2894 LM5026: the datasheet indicates 2 reset possibilities: P-MOSFET & N-MOSFET.
Plenty of examples for the P-MOSFET and it works.
Not a single example for connecting the N-MOSFET and any attempt…
